Abstract: We study real massive antisymmetric tensors of rank two in holographicmodels of QCD based on the gauge-string duality. Our aim is to understand indetail how the AdS-CFT correspondence describes correlators with tensorcurrents in QCD. To this end we study a set of bootstrapped correlators withspin-1 vector and tensor currents, imposing matching to QCD at the partoniclevel. We show that a consistent description of this set of correlators yieldsa very predictive picture. For instance, it imposes strong constraints oninfrared boundary conditions and precludes the introduction of dilatonicbackgrounds as a mechanism to achieve linear confinement. Additionally,correlators with tensor currents turn out to be especially sensitive to chiralsymmetry breaking, thus offering an ideal testing ground for genuine QCDeffects. Several phenomenological consequences are explored, such as thenontrivial interplay between $1^{+-}$ states and conventional $1^{-}$ vectormesons.
